Product Overview
The Rexroth Z2S6-1-66/V/760J3 (Material No. R901429695) is a pilot operated check valve designed for leak-free load holding and controlled flow in hydraulic systems. As part of the Rexroth Z2S series, this valve is a modular sandwich plate component that blocks flow in one direction and permits free flow in the opposite direction when a pilot pressure is applied. The Z2S6-1-66/V/760J3 is engineered for reliable load holding, preventing actuator drift and uncontrolled movement in demanding industrial applications. Its modular design allows direct mounting between a directional control valve and a subplate, making it an ideal choice for compact hydraulic power units and manifold assemblies.
